Only few examples of organocatalysts for the synthesis of cyclic carbonates via the coupling of CO2 and epoxides under the mild condition of room temperature have been reported in the literature. However, they needed high level of catalyst loading (＞5 mol%), elongated reaction time(＞18 h), or high CO2 pressure (＞10 bar). Therefore, the development of new catalytic systems at milder condition would be required for a true green chemical process. We have developed novel bifunctional one-component organocatalysts that resemble scorpions effectively couple carbon dioxide and epoxides under room temperature, low-catalyst-loading (2 mol%), low-carbon-dioxide-pressure (1–10 bar), and solvent-free conditions.1 Further details will be provided in the presentation.
